ICD-10 Code H18.833 – Recurrent erosion of cornea, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.833 – Recurrent erosion of cornea, bilateral
What it is
H18.833 identifies recurrent erosion of the cornea in both eyes. It means the corneal surface repeatedly breaks down, often causing sudden discomfort and irritation.
Clinical signs
Typical findings include recurrent eye pain, tearing, light sensitivity, and a foreign-body sensation, often on waking. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents recurrent corneal erosion affecting both eyes. It applies when the condition is bilateral and not simply a one-time abrasion. If the note does not clearly state laterality or recurrence, check documentation.
Do not use for
Do not use H18.833 for a single corneal abrasion or for erosion documented in only one eye. Do not assume bilateral involvement unless it is clearly stated.
Coding tip
Confirm both recurrence and bilateral laterality in the record before assigning H18.833.
